, PUMP.

SPECIFICATION forming part of Letters Patent N o. 272,343, dated February 13, 1883.

Application filed September 18, 1882. (No model.)

inafter described, and pointed out in the claims. v

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.

Figure l is a sectional elevation of our improved pump. Fig. 2 is a horizontal section of the cylinder, and Fig. 3 is a horizontal section of the piston-rod on the line ma' of Fig. l. Y

rlhe cylinder a is made large to contain a sufficient supply of water in a charge for the supply of the user for a time, and is placed upright in the cistern orwell, or sufficiently near the water therein for suction, and is provided with suction-valves b and av deliverypipe, c, connected thereto at the bottom. The piston d has a rod, e, extending up through ses the top of the well, and has a toothed rack,f, on the upper part, with which a pinion, g, gears, which'pinion is operated by a crank, h, on its shaft. By this means the piston, with the weights to be placed in the basket i, is raised and the spring l1. compressed so that when the pinion is disengaged from the rack on the piston-rod the piston d will be forced down by the combined action of the weights and spring, and cause the discharge of the water out of the pipe j, the said weights and spring (one or both) being employed to expel the water as it is wanted out of the pipe 7', from which it may be allowed to escape when wanted by a cock, k.

The pinion g is mounted on a shaft, g,jour

naled in boxes l, which are provided with slots l', through'which the bolts l2, by which the-boxes are secured to the bracket, pass. The boxes are connected together and to a camlever. By this construction the boxes can be moved on the bracket by the said lever to throw the pinion into gear with the racket the piston when it is desired to raise the same, and out of gear when the piston is to be allowed to descend.'

With a pumping device of this contrivance Water may be supplied to circulating-pipes, basins, and tubs throughout ahouse substantially as well as from a cistern overhead, into which the water is pumped from time to time, thus saving the expensive construction of an overhead cistern.

Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent- 1. Thecombination, with the cylinder-nl and the discharge-pipe c j, of the piston d, the

'weight and spring-pressed piston-rod e, and

means for elevating said rod and disengaging it from its elevating mechanism, substantially as herein shown and described, whereby the piston will be forced' down by the combined action of the spring and weight, as set forth.

2. The combination, with the cylindera and the discharge-pipe c j, provided with the stopcock 7e, ot' the piston d, piston-rod e, provided with the basket i and the spring h', surrounding the said rod, and means for elevating the said rod and disengaging it' from its'elevating mechanism, substantially as herein shown and described.

3. The combination of the rackf, pinion g, crank h, sliding box l, and the eccentric lever n, substantially as described.
